Culinary Cremini Mushrooms

Cremini mushrooms sometimes live in the shadows of their well-known edible relatives. They're not quite the common white button, but they're not quite the larger brown portobello either.

Yet did you know that all three belong to the same species,Agaricus bisporus? Cremini, also known as crimini mushrooms, are simply a different strain than the white button. Developed by commercial growers, they are brown in color and have a slightly deeper taste.

Growers also created the concept of portobello mushrooms to sell mature cremini. A portobello is just an older mushroom that has grown until the cap has expanded. That's why cremini are often labeled as "baby portobello" or "baby bella". Ah, advertising!

Basic Facts

Cremini mushrooms strongly resemble the common white button, only with a brown cap. The Latin name for both is Agaricus bisporus.

They have a deeper, heartier flavor and firmer texture than white button mushrooms. If you find the white grocery store mushrooms boring or too soft, try substituting cremini.

They are saprotrophs, meaning they feed on dead and dying material. You'll find them in fields and grasslands throughout the world.

Cremini mushrooms are widely cultivated but there are wild strains. They fruit from late spring to fall.

They produce a brown spore print.

These are great "learning mushrooms". Easily obtained at the grocery store, dissect them for a mushroom anatomy lesson.

If hunting for them in the wild, be careful not to confuse them with a deadly Amanita. Two big differences are that amanitas have a cup, or volva, around the base (cremini do not) and white gills (cremini gills are usually brown).

Uses for Cremini Mushrooms

Although not famous medicinal mushrooms like their reishi or maitake cousins,cremini do appear to be beneficial to the body.

There's evidence that Agaricus bisporus inhibits aromatase, an enzyme that contributes to estrogen production. By controlling estrogen levels, the risk of breast cancer is lowered. See this page for a brief write up on a study done on decreasing tumor cells. (Be warned it contains harder science than some may have an interest for).

Beyond medicinal, the main uses for these mushrooms are culinary. These are famous edibles, and good for you as well. They're known to contain:

Vitamin D

Potassium

B Vitamins

Helpful antioxidants like selenium

Fiber

Linoleic acid (believed to be responsible for controlling estrogen levels)

These health benefits, along with great taste, make cremini mushrooms a welcome addition to many meals. Use them with eggs, meats, or vegetable dishes. They're also excellent in soups, gravies, and stir-fries.

Another aspect that makes them great for cooking is that they're very common in grocery stores. You won't have to spend a day in the woods to have them for dinner, although I admit that is part of the fun!

Once purchased, store them in the refrigerator in a paper bag for up to a week. Never store mushrooms in plastic, as plastic doesn't "breathe" and you'll soon experience great disappointment when your mushrooms are mushy and gross.

A final note on eating cremini, do be aware that Agaricus bisporus contains small amounts of toxins (gyromitrin for example). These toxins are rendered to negligible levels by heat so always cook your mushrooms. Many sources will tell you it's safe to eat them raw, but the truth is it's best to cook your mushrooms.

Don't let that turn you off too much. Once cooked, mushrooms are quite safe. People have been eating them for years.
